As a customer, I use Odoo for various purposes in my company, ranging from accounting to sales. I use it as accounting software, CRM, and sales software. I also host my website on it and manage product and service offerings, primarily selling services.
I utilize the social media applications and note mailing address feature for marketing purposes and maintain records through a Wiki-like feature. For document management, I employ the scanning and automatic OCR task functions.
Overall, I use almost all the functionalities except for the warehouse feature because I don't handle tangible products. As an integrator, I assist clients with warehouse solutions, implementing tools to monitor stock and other modules among the sixty available in Odoo.
